Figure Lengend Snippet: Figure 4: Integrative transcriptomics analyses of ESCC cells following pharmacological or genetic inhibition of LSD1 and G9a. (a) RNA-seq analysis was performed on ESCC cells in which either LSD1 expression was knocked down using shRNA or LSD1 was inhibited with SP2509; differentially expressed genes were determined by comparing with ESCC cells expressing a control nonsilencing shRNA (shNC) and vehicle-treated ESCC cells, respectively, and are summarized using Venn diagrams. (b) Gene Set Enrichment Analysis of the overlapping differentially regulated genes in (a). (c) Heatmap of the differentially expressed genes in the “cell death,” “apoptosis,” and “ER stress” pathways. (d–f) Same as (a–c), except G9a was knocked down using shRNA or inhibited with UNC0642. (g–i) Same as (a–c), except both LSD1 and G9a were knocked down with shRNA or both LSD1 and G9a were inhibited with SP2509 and UNC0642.

Article Snippet: The following reagents were also used: hematoxylin and eosin (H&E) staining kit (Beyotime Biotech), TdT in situ apoptosis detection kit (R&D Systems, Minneapolis, MN), TRIzol reagent (Pufei Biotech, Shanghai, China), SYBR Green Supermix (Bimake, Houston, TX), RIPA buffer (Beyotime Biotech), protease inhibitors (Bimake), BCA protein assay kit (Beyotime Biotech), polyvinylidene fluoride (PVDF) membranes (Bio-Rad, Hercules, CA), Pierce ECL System (Thermo Scientific, Waltham, MA), EdU Kit (Ruibo Biotechnology Co., Ltd., Guangzhou, China), cell cycle staining kit (Multi Sciences Biotech, Hangzhou, China), annexin V-FITC/PI apoptosis detection kit (Multi Sciences Biotech), and PrimeScript RT reagent kit (Takara, Kyoto, Japan).

Figure Lengend Snippet: Figure 5: Inhibiting both LSD1 and G9a in ESCC cells induces S-phase arrest and apoptosis. (a) Summary of the percentage of ESCC cells in the G1, S, or G2 phase after the indicated treatments for 2 days. SP2509 5 μM, UNC0642 5 μM. (b) Western blot analysis of the indicated cell cycle-associated proteins in ESCC cells treated as indicated. (c) EdU staining of ESCC cells treated with vehicle, 3 μM SP2509, 1.2 μM UNC0642, or both for 2 days; the nuclei were counterstained with Hoechst 33342. (d) Apoptosis analysis of ESCC cells after the indicated treatments for 2 days. (e) Western blot analysis of the indicated apoptosis-associated proteins in ESCC cells treated as indicated for 2 days. (f) Quantification of the indicated proteins measured in (e), expressed relative to vehicle-treated cells. (g) Representative images of ESCC cells treated with vehicle, 10 μM SP2509, 10 μM UNC0642, or both for 2 days. (h–k) Representative transmission electron microscopy images of ESCC cells treated as in (g); mitochondria (M) and endoplasmic reticulum (ER) are indicated. The scale bars are 5 μm in (h), 2 μm in (i–k). ∗p < 0:05, ∗∗p < 0:01, and ∗∗∗p < 0:001 (unpaired Student’s t-test).

Figure Lengend Snippet: Figure 4. Quantification and antimicrobial activity test of hCST3 in transgenic chickens. (A) Quantification of hCST3 in the egg white (EW) of transgenic hens by ELISA. hCST3 was detected in all of the transgenic hen eggs. (B) hCST3 was detected in the muscle of hCST3 transgenic chickens by Western blotting. (C) His-tagged hCST3 in muscle and egg white of hCST3 transgenic chickens was purified and detected by Western blotting after purification with Ni-NTA magnetic nanobeads. (D) Biofunctional activity of hCST3 from transgenic hen eggs. The purified hCST3 from transgenic hen egg white was transferred to Whatman paper disks at different concentrations: (1) control (ddH2O), (2) elution buffer, and (3) 10, (4) 25, (5) 50, (6) 75, and (7) 100 ng hCST3/disc. Original western blot figures in Figure S1.

Article Snippet: hCST3 protein in cells and transgenic chickens was detected and the concentration was determined by using human cystatin C Quantikine® ELISA Kit (R&D Systems, Minneapolis, MN, USA) according to the manufacturer’s protocol.
